A chalcone based chemosensor was reported, and its in situ formed complex can serve as a cyanide anion probe.
A highly selective and sensitive fluorescence quenching chemosensor (ACC) for Cu2+ detection in HEPES buffer and living cell imaging was developed.
Water soluble L–Au–DNA nanohybrid exhibits enhanced 2PA properties that can widely and evenly uptake into the lysosome of HepG2 cells.
